data-id=common-pdf-settings

Common PDF Settings

This chapter describes the Adobe PDF settings that belong to the Common namespace. (See Namespaces.) These settings have historically been documented in Acrobat Distiller Parameters. They are supported by Distiller and may be supported by one or more of the applications in the Creative Suite, version 2.0 and later. The settings in other namespaces are described in Other Namespaces.

The settings are grouped into the same categories that appear in the Distiller user interface (UI). The Creative Suite applications have similar interfaces for PDF creation settings, although they may differ in some respects. More information on the use of Adobe PDF settings can be found in Help for Distiller and the Creative Suite applications.

data-id=36016

data-id=settings-descriptions

Settings descriptions

The possible values for the settings are enumerated, with their meanings.

Supported by

Indicates which of the applications (Distiller, Illustrator, InDesign, and Photoshop) support this setting.

Type

The type of data. The types are consistent with PostScript syntax and can include Boolean, number, string, array, and dictionary.

UI name

The name (if any) of the user interface control that corresponds to this setting. (There can be slight variations based on application)

Default value

Each setting has a default value, which is the value that is used when a setting is not specified in the settings file.

Note

The default values are the same as those in the Standard.joboptions file, with the following exceptions:

• NeverEmbed defaults to [true] (no list of fonts)
• Description is not provided
• TransferFunctionInfo defaults to Preserve
• CompressObjects defaults to Off
• CalGrayProfile defaults to ()
• PassThroughJPEGImages defaults to false

data-id=general-settings

General settings

These settings are available in the General panel of the Distiller settings dialog box. Those settings that are supported by Creative Suite applications are indicated.

data-id=autorotatepages

AutoRotatePages

Allows Distiller to automatically orient (rotate) pages based on the predominant text orientation. Auto-rotation is not done if the file contains the %%ViewingOrientation DSC comment and ParseDSCComments is true. If AutoRotatePages is set to None, pages are not automatically oriented and the %%ViewingOrientation DSC comment is ignored.

data-id=endpage

EndPage

The last page of the document to be produced.

StartPage and EndPage together determine the range of pages in the PostScript file that are converted to PDF. If StartPage is greater than 1 (the default), no PDF output is produced for the first (StartPage -1) pages of PostScript. StartPage becomes page 1 of the PDF file. If EndPage is greater than -1, distilling stops after the EndPage of PostScript. Distiller checks these two settings at the time that the first PostScript marking operator is executed in a job.

Note

StartPage and EndPage are useful when debugging PostScript. They are not recommended for general purpose use, as Distiller does not retain page number references in document links.

Note

Embedding is subject to license; specific fonts can indicate that embedding is not permitted.

data-id=41375

data-id=alwaysembed

AlwaysEmbed

An array consisting either entirely of font names, or of a Boolean value followed by font names. Each name is the PostScript language name of the font (the name given to definefont).

• If the array consists entirely of names, Distiller sets its internal list of fonts that must be embedded to be exactly the list of names in the array.
• If the first array value is the Boolean true, Distiller adds the font names in the rest of the AlwaysEmbed array to its internal list of fonts that must be embedded.
• If the first array value is the Boolean false, Distiller removes the font names in the rest of the AlwaysEmbed array from its internal list of fonts to be embedded.

data-id=maxsubsetpct

MaxSubsetPct

The maximum percentage of glyphs in a font that can be used before the entire font is embedded instead of a subset. The allowable range is 1 through 100.

Distiller only uses this value if SubsetFonts is true. For example, a value of 30 means that a font will be embedded in full (not subset) if more than 30% of glyphs are used; a value of 100 means all fonts will be subset no matter how many glyphs are used (because you cannot use more than 100% of glyphs).

NeverEmbed

An array consisting either entirely of font names, or of a Boolean value followed by font names. Each font name must be the PostScript language name of the font (that is, the name given to definefont).

• If the array consists entirely of names, Distiller sets its internal list of fonts that must never be embedded to be exactly the list of names in the array.
• If the first array value is the Boolean true, Distiller adds the font names in the rest of the NeverEmbed array to its internal list of fonts that must never be embedded.
• If the first array value is the Boolean false, Distiller removes the font names in the rest of the NeverEmbed array from its internal list of fonts to never be embedded.

data-id=subsetfonts

SubsetFonts

If true, font subsetting is enabled. If false, subsetting is not enabled. Font subsetting embeds only those glyphs that are used in a document, instead of the entire font. This reduces the size of a PDF file that contains embedded fonts. If font subsetting is enabled, the application determines whether to embed the entire font or a subset by the number of glyphs in the font that are used (including component glyphs referenced by ‘seac’ [Type 1] glyphs), and the value of MaxSubsetPct.

Subsetted fonts in the PDF file appear with a 6-letter prefix and a plus (+) sign. For example, Palatino subsetted may appear as:

If true, Distiller produces a Job Definition Format (JDF) file that reflects the parameters used for distillation. If false, a JDF file is not produced.

The Job Definition Format (JDF) Specification is owned and maintained by the International Cooperation for the Integration of Processes in Prepress, Press and PostPress (CIP4) (www.cip4.org). Distiller 7.0 complies with JDF Specification Version 1.1 Revision A, published on September 5, 2002. It is available on the web at:

http://www.cip4.org/documents/jdf_specifications/index.html

Note

The Acrobat 7 Professional product now supports creation of both JDF 1.1- and JDF 1.2-compliant JDF files. For more information, see the Acrobat Guide in Distiller online Help.

The Adobe Normalizer product (see Using Adobe Normalizer Server, Version 6.0.4) is also capable of producing JDF files, but it can consume them as well. Conversions Related to JDF,” describes how Normalizer interprets and converts Distiller parameters; use this information to understand the JDF file created by Distiller.

The JDF file is output to the current directory with the .jdf extension. The filename is the same as the .log file and the file that is being distilled. (The “current directory” is the directory where the new PDF file is output.)

Note

The JDF pdfmark allows the PostScript file/stream being distilled to specify certain elements and attributes to be added to a JDF file. For details, see Using Adobe Normalizer Server, Version 6.0.4 and the PDFMark Reference.

data-id=detectblends

DetectBlends

If true, Distiller enables the conversion of PostScript gradients to smooth shades. If false, Distiller disables conversion.

Note

If CompatibilityLevel is less than 1.3, Distiller disables conversion regardless of the value of DetectBlends. In addition, Distiller always disables conversion if idiom recognition is turned off in the prologue file or in the PostScript file itself.

Distiller uses two methods to perform the conversion of gradients to smooth shades:

• The PostScript Language Level 3 feature called idiom recognition replaces certain procedures (idioms) with others having equivalent behavior but producing better quality results. (See “Idiom Recognition” on page 119 of the PostScript Language Reference for details.) DetectBlends enables the subset of idioms that detect gradients (or blends) for the following applications: Adobe Illustrator, Adobe Freehand, CorelDraw, and QuarkXPress.
• Distiller also converts gradients to smooth shades independently of idiom recognition. This method is application-independent, but it is less reliable than the first.

In Distiller 4.0, the blend detecting idioms (first method) was controlled by the IdiomRecognition PostScript feature, while the second method was controlled by DetectBlends. You had to turn off IdiomRecognition to use DetectBlends.

In Distiller 5.0 and above, DetectBlends controls the blend detecting idioms. By default IdiomRecognition is turned on in Distiller 5.0 and above, and the blend detecting idioms are controlled using DetectBlends. You can still use the PostScript feature IdiomRecognition with the setuserparams operator, if needed.

data-id=detectcurves

DetectCurves

The value of this setting must be in the range from 0.0000 to 10.0000. If the value is 0.0000, the feature is disabled. If positive, Distiller investigates graphics for curves that are not described efficiently and thus result in unacceptably large file sizes. Distiller converts these curves into bezier curves that take up much less file space.

This setting represents a value in user space (72 dpi) that controls Distiller’s curve-fitting algorithm: the curve-fitting results should not part from the original line segments by more than this number. Visual inspection of the results suggests that the 0.1000 value yields the closest approximation to the original curve.

Note

Distiller ignores this setting if ParseDSCComments is false.

Distiller 4.0 and higher places the Document Information in the Info dictionary of the PDF file; you can view the information in Acrobat by clicking File > Document Properties. Starting with version 5, Distiller also embeds the Document Information as XML in the PDF file. To embed the information, Distiller adds a Metadata key in the Catalog dictionary whose value is an indirect reference to a metadata stream object. The metadata object contains the metadata (the Document Information) for the PDF document. The metadata is represented as RDF, in conformance with Adobe’s Extensible Metadata Platform (XMP).

data-id=38057

data-id=passthroughjpegimages

PassThroughJPEGImages

If true, JPEG images (images that are already compressed with the DCTEncode filter) are “passed through” Distiller without re-compressing them. (Distiller does perform a decompression to ensure that images are not corrupt, but then passes the original compressed image to the PDF file.) Images that are not compressed will still be compressed according to the image settings in effect for the type of image (for example, ColorImageFilter, etc.).

If false, all JPEG encoded images are decompressed and recompressed according the compression settings in effect.

Note, however, that JPEG images that meet the following criteria are not passed through even if the value of PassThroughJPEGImages is true :

• The image will be downsampled.
• ColorConversionStrategy is sRGB and the current PostScript color space (for the image) is not DeviceRGB or DeviceGray.
• The image will be cropped—i.e., the clip path is such that more than 10% of the image pixels will be removed.

Creative Suite applications do not use this setting. However, Illustrator and InDesign normally behave as if it were true with regard to placed PDF files containing compressed images. That is, they do not normally uncompress and recompress them, unless color conversion or downsampling takes place.

Passing through JPEG images has these advantages:

Performance : Only decompression and not recompression occurs.

No loss of image data : DCT encoding inherently causes some loss of data; thus, with this option, since no recompression occurs, no data is lost.

No loss of metadata : When Distiller decompresses an image, all metadata is discarded; thus, with this option, no metadata is lost since no recompression on the decompressed image occurs.

Note

Distiller’s hard-coded default value of PassThroughJPEGImages is false to conform to older settings files where this setting did not exist. Most predefined Adobe PDF settings files set it to true. The Smallest File Size settings file sets it to false since that generally results in smaller file sizes. However, in some cases this setting could actually increase file size, for example, if the original JPEG in the PostScript file was compressed with a Quality setting lower than the Quality setting in the settings file.

If true, and ParseDSCComments is true, Distiller attempts to preserve the encapsulated PostScript (EPS) information in the PostScript file as properties of the resulting PDF file. The distilled EPS content is identified as marked content using the EmbeddedDocument key.

The following table lists this information.

Starting with version 5, Distiller also embeds the information for embedded EPS files as XML in the PDF file. To do this, Distiller performs the following tasks:

• Adds a Metadata key in the property list of the marked content container for the EPS.
• Stores the property list as an indirect reference in the page resources object.

The value of the Metadata key is an indirect reference to the metadata stream object, which contains the metadata (the EPS information). The metadata is represented as RDF, in conformance with Adobe’s XMP.

If true, Distiller places the page contents within a set of Open Prepress Interface (OPI) comments in a Form XObject dictionary and preserves the OPI comment information in an OPI dictionary attached to the Form. Page contents data within a set of OPI comments may include proxy images, high-resolution images, or nothing.

If PreserveOPIComments is false, Distiller ignores OPI comments and their page contents. Setting PreserveOPIComments to false results in slightly simpler and smaller PDF files. Doing so is acceptable when use of an OPI server is not anticipated.

Distiller ignores PreserveOPIComments if ParseDSCComments is false.

Distiller recognizes both OPI 1.3 and OPI 2.0. See the specifications for OPI 1.3 and 2.0 (TN #5660).

For Creative Suite applications, CheckCompliance also takes precedence over values of other settings (such as ColorConversionStrategy or CompatibilityLevel) that could potentially result in a file that is not compliant, and the values of the other settings are adjusted accordingly.

PDFX1aCheck

If true, checks compliance with the PDF/X-1a standard (ISO 15930-1:2001) and a PDF/X compliance report is written to the message log.

A value of /PDFX1aCheck true is equivalent in Distiller 7 to a value of /CheckCompliance [ /PDFX1a:2001 ].

Note

This setting is retained for compatibility with Distiller 6. For more information on how this setting works, see Using the standards settings.

PDFXOutputIntentProfile

This setting indicates the characterized printing condition for which the document has been prepared and is required for PDF/X compliance. The value may be one of the following:

• The name of a specific profile. The UI lists a number of available profiles. This is the only value supported by Creative Suite applications.
• (Use Output Condition Identifier) The profile is specified by PDFXOutputConditionIdentifier. This value is used by Distiller only.
• (None) This value should be used for workflows that require the output intent dictionary to be specified in the PostScript document and that require compliance checking to fail if it is not specified. In the UI, it corresponds to “No Default Profile”. This value is used by Distiller only.

PDFXTrapped

Indicates the state of trapping within the file. Can be one of the following values:

Note

True and False are name objects, not the Boolean values true and false.

A value of True or False is required for PDF/X compliance. If the PostScript file does not specify that the document is trapped, then the value provided here is used. Unknown should be used for workflows that require that the document specify a trapped state and for which compliance checking should fail if it is not present in the document.

Note

Illustrator can set this value to True or False via “Mark as Trapped.” InDesign always specifies False for PDF/X compliant files.
